IMPROVEMENT |N cuLTlvn-ous.`

S pecication forming part of Letters Patent No. 144,710, dated November18, 1873; application filed September 6, 1873.

To all whom it may concern:

Be it known that I, R101-IARD S. GAvET-I, of Bedias, in the county ofGrimes and State of Texas, have invented a new and valuable Improvementin Plows; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a representation `of my plow. Fig. 2 is atop view of same.

Fig. 3 1s a back view of same.

The object of this invention is to connect together the beams andstandards of gang plows or cultivators by means of loose joints orlinks, for the purpose of allowing the plowman to manipulate the plowsas he may find it necessary.

In the annexed drawing, A A represent two beams, which are parallel toeach other, and to the rear ends of which inclined standards B B arerigidly secured, carrying on their lower ends cultivator-shovels b b.Handles C C are also secured to the two beams A A, and to the upper endsot' the two standards B B, by means of which the shovels aremanipulated. Outside of these beams A A, and running parallel thereto,are two more beams, A A', whose standards B B carry shovels b b', andare somewhat bent for the purpose of allowing their upper ends to bearranged in line with the corresponding ends of the standards B B. Thetwo intermediate standards are connected together by a link, h, which ispivoted at la h', and the two beams A A are connected together by alink, g, which is pivoted at g g. The front ends of these beams haveeyes c e connected to them by means of straps c c, and to the eyes adraft-clevis, d, is linked. The holes through the beams A A andstandards B B, for the receptionof the `links g h, are suiciently largeto allow said parts to receive free longitudinal and vertical motion, sothat one shovel may be advanced beyond the other, or raised above theother, while the machine is being drawn along between the rows.

The outside beams are attached to their respective intermediate beams bymeans of a loose-jointed link, h, and a shackle, p a, and

the upper end of each standard B is attached i to its adjacent standardB by means of a link,

ble laterally by means of supernumerary holes i through the severallinks g li. The drawings represent a four-shovel gang-'cultivator, butthe improvement is applicable to various kinds of plows and cultivators.y

I disclaim the devices shown in the patent granted to Thos. McQuiston,dated October 1S, 1859.

What I claim as new, and desire to secure byu Letters Patent, is

The combination of beams A A A A and standards B B B B with the looselink-connections g h e e d and p a, as and for the purposes described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
